Intraocular Pressure and Choroidal Thickness Respond Differently to Lower Body Negative Pressure During Spaceflight

Spaceflight induces a chronic headward fluid shift that is believed to underlie ocular changes observed in astronauts. The present study demonstrates, for the first time, that reversing this headward fluid shift via application of lower body negative pressure (LBNP) during spaceflight may alter the...
